[Main Thread] Can't launch the Battle.net App - DLL error

Battle.net.13434
Win7 PC (worked fine 10h ago)

Error: Cannot launch the Battle.net App.
“A required DLL could not be found. Please download and reinstall the Blizzard app.”

Done so far:

  1. Uninstall
  2. Reinstall
  3. Uninstall
  4. Removed ALL registries related to Blizz/Battle
  5. Removed C:\Program Files (x86)\Battle.net → Battle.net.13434
  6. Reinstall
  7. Installed Visual Studio 2015, 2017, 2019, and 2022
  8. Checked drivers
  9. Removed C:\ProgramData\ → Battle.net
  10. Removed %appdata%
  11. Reinstalled

Copied the Battle.net.13401 folder from a Win10 laptop to the Win7 PC folder and removed the 13434 folder.
DLL error came back on along with the Battle.net.13434 folder.
Started app again (w/o removing the 434 folder) and it got me to the Login Screen → Queue time… → Battle.net open → Can’t locate games → Folder with games… → Battle.net open but freezes and imediatelly started to update. Clicked on Play under HotS and I was in.

Dear Blizz…pls fix ur stuff asap as I’m pretty sure I’m going to run into this again as soon as I need to restart the app! :triumph:
